From Columb's Law which describe the electrostatic interaction.
The formula is given and looks as follows
where:
F is force acting between charges,
q1 - charge one given in columbs,
q2 - charge two given in columbs,
r - distance between charge in meters
k - constant
First, we have to convert out formula to get r.
Now we multiplaty by
both sides of equation
Now we devide both sides by F
Next step is take square root
We have all date, we can subsitute it to our formula
It was Niels Bohr who proposed it
Because tropical moist forests are used for agricultural, the thin soil cannot support continuous cropping, while deciduous forests can regrow quickly.
